There are five confirmed monster mutations in Catch a Monster: Shiny, Huge, Bloodlit, Corruption, and Fairy. Every time you obtain a pet, there’s a small chance that it could have any of the above mutations. The base chances of getting a mutated monster increase during the Bloodmoon Weather Event. Mutations will change the appearance of the monster and boost certain stats like Attack, HP, Crit Rate, and more.
